Cytoplasmic and Evolutionary Genetics
The research group of Dr. Stephan Greiner "Cytoplasmic and Evolutionary Genetics" focuses on molecular and mechanistic aspects of plant evolution. We concentrate predominately on the role of cytoplasmic genetic elements (plastids and mitochondria) in speciation processes.
The choice of an appropriate model organism – Oenothera (evening primrose) – allows novel approaches to elucidate the mechanisms underlying reproductive isolation mediated by the cytoplasm and its role in speciation.
However, questions in Oenothera are not limited to the impact of organelles. Studies of important aspects of plant evolution, including early diversification of populations and the evolution of sex are feasible. In addition, the model allows us to pursue some applied aspects, like plastid-mediated cytoplasmic male sterility, suppression of homologous recombination in meiosis, and plant breeding for medical uses.
